VAPOR GONDENSER yIEOR MOTOR VEHICLE RADIATORS.

Application filed March 3, 1926. Serial No. 91,992.

This invention relates to a vapor condenser for attachment to theusual filler neck of a motor vehicle radiator, and has for its primary object to provide Va device that is incorporated within a conventional design of motor meter in order that the two units may be combined into one instrument and this without detracting from the appearance of the universally used motor meter. v

An additional object of the invention is to provide an instrument wherein the same is so vconstructed as to present at itsrear side a meter for determining the heat of the fluid within the radiator and at its forward side means for condensing the vapor of alcohol or other anti-freezing preparation thereby ypreventing the wastage of such antifreezing solution which occurs when the vapor is permitted to escape tothe atmosphere. i

A further object is-to provide such an instrument that is of ahighly ornamental nature and that is well adapted for all of the purposes for which the same is intended.

lNow having particular reference to the drawing: i c

Figure 1 is a rear. elevation ofan'instrument constructed in accordance with the present invention.

vFig. 2 is a View partly in vertical cross section and partly in front elevation of the instrument.

Fig. 3 is an enlarged fragmentary longitudinal section of a horizontalvvapor-pipe included in the present invention, theopposite endsthereof being provided with pressure controlled valves nfor perinittingthe escape of the vapor should the pressure of the same within the engine reach a predetermined high degree, and a.

v Figure l is a central vertical section taken on line 4.-'-4 of Figure 2.

Now having particular reference. tothe drawing, my novel instrument comprises a circular metallic case 5, having. its sides closed by glass plates and provided with a central partition wall 6 for dividing the same into front and rear compartments. Within the rear compartment is a therinoineter vial 7 arranged vertically at the center thereof, the lower end of which .ext-ends through the bottom edge of the casing and portion 12, and a zig-zag portion 18 at portion of strict the passage of lzig-zag portion resulting in the more efinto a. radiator filler neck attaching sleeve 8 that is formed upon or otherwise secured to the lower side of said casing as Vclearly shown in both Figs. 1 and 2. This sleeve is internally threaded for lpermitting the threaded engagement of the same with the usual externally threaded radiator filler neck n while said sleeve is further provided with the usual knurled flange 9 for facilitating the turning of the sleeve onto or from said radiator filler neck. Y

Arranged upon the rear side of the casin .5 in front of the thermometer 7 is the usua protecting circular glass plate 10.

Arranged within the front compartment 'of the casing 5 is a vapor condensing coil '11 formed of a single length of piping as clearly shown in Fig. 2. This coil is so constructedas to provide a relatively C-shaped diametrically opposed sides of the casing, the C-shaped portion 0f the condensing coil being of greater cross sectional area than the the piping forming the zig-Zag portion 13.

The ends of the piping forming the coil pass through the casing 5 and enter the sleeve 8 also as shown in Fig. 2. The end of the C-shaped portion 12 is flared outwardly as at 15 to provide a receiving funnel for the'vapoisbeing discharged from the radiator while the end Yof the zig-Zag portion of the pipe coilis equipped with a pan 16 in which condensate forms a liquid seal which prevents the entrance of the vapors into this endof the coil'.v

Arranged within the funnel end 15 is a screen 17 which will prevent the entrance of shale or other foreign matter into the coil. The reason for the .variation in cross sectional area between the Zig-zag portion and C-shaped portion of of' the ready passage ofthe vapors into and through said C-shaped portion but to rethe vapors through the icieiit condensing of the vapors being discharged from the radiator.

Extending longitudinally across the attaching sleeve 8 above the knurled flange 9 is a horizontal pipe 18 that communicates the coil is to permit with the condenser ,pipe adjacent the inlet initting vthe passage of the in front of the condensing coil is a circular glass plat-e 20, the edge of Which-rests Within arabbet formed in the casing as clearly shown in lig. 2, said plate being secured in Waterl-tight-manner by reason of a conventional retaining ring 2l.

l:Directly above the compartment.containing thevcondensing coil 'is a threaded opening 22 Within Which-is arranged a threaded plug 28, said opening being provided to permit the filling of the coil compartment with a cooling fluid such as Water or the like, which will assisttlie air in maintaining the coil cold facilitating the entire condensation of the vapors passing therethrough.

It Will thus be seen that l have provided a highly novel, simple and eiicient form of vapor condenser, for vehicle radiators, 'that is so Vconstructed as to ei'iiciently combine with a more or less conventional type of motor meter in order that all of the objects and purposes heretofore set out Will be completely attained.

Even though l have herein shown and described a specific form of my invention,

it is nevertheless to be understood that minor changes may be made Without aifecting the spirit and scope of the invention as hereinafter claimed.

Havingvthus described my invention, what l lclaim as new and desire to secure by Letters Patent is l.A ln an instrument of the character described, a casing, a sleeve upon the lower side of VJthe casing to facilitate its association With a motor vehicle radiator iiller neck, a condensing coil arranged Within the casing and having its ends projecting therethrough and into said attaching sleeve, and means upon one end of said condenser for preventing the entrance of vapors into this end.
